ABSTRACT:
A vibration-wave drive motor incorporating a multilayer piezoelectric element having reduced vibration damping as well as a design lending itself to reduced manufacturing costs and miniaturization. The multilayer piezoelectric element includes a piezoelectric active part formed by a plurality of piezoelectric layers having an internal electrode, and a piezoelectric inactive part formed by an integrated piezoelectric layer with no internal electrodes. The vibration-wave drive motor consists of a vibration body including the multilayer piezoelectric element, and a contact body press contacting the vibration body.
